Union Alpha scores 74 on DeepSWE matching GPT-6 Astra, but benchmark may be saturated

- A leak describes a mystery model Union Alpha: 74 on DeepSWE (matching GPT-6 Astra), free for now with zero data retention, available via opencode, OpenRouter, and Cloudflare AI Gateway, with claimed 5T tokens/day capacity.
- It reportedly lands 50% on terminal-bench v4 at $1.5-2/task.
- Brandon Galang argues DeepSWE is saturated at 74% since several clearly weaker models match that score — the last 26% is likely broken and the benchmark needs updating.
